The California department of Food and Agriculture has issued a Quarantine to prevent the entry of Japanese Beetles from our county in Alabama.
Following is the content of their website addressing this issue.
Because our plants are grown for edible purposes, we do not feel that we can comply with this requirements below to certify our plants so they could be allowed into California.
C. Articles and Commodities Covered. The following are hereby declared to be hosts and possible carriers of the pest quarantined against:
1. Soil (except when commercially packaged). For the purpose of this section, soil shall mean all growing media;
2. Humus, compost and manure (except when commercially packaged);
3. All plants with roots (except bareroot plants free from soil); "Free from soil" as used in this regulation shall mean free from soil in amounts that could contain concealed Japanese beetle larvae or pupae:
4. Grass sod;
5. Plant crowns or roots for propagation (except when free from soil);
6. Bulbs, corms, tubers, and rhizomes of ornamental plants (except when free from soil);
7. Any other plant, plant part, article, or means of conveyance when it is determined by a California State Plant Quarantine Officer to present a hazard of spreading live Japanese beetle due to infestation or exposure to infestation by Japanese beetle.
1. Certificate of Treatment. All of the articles and commodities covered are approved for entry into California when accompanied by a certificate issued by an authorized state agricultural official stating that the article or shipment was treated for Japanese beetle prior to shipment or by a certificate issued by an authorized state agriculture official at origin stating that the article or commodity shipped was grown in accordance with methods and procedures approved and prescribed by the Secretary. (See Appendix A).
APPENDIX A 10-28-98
All pesticide products must be labeled in the state where treatments are applied, and must be used in strict accordance with product labeling instructions and worker protection standards. Nothing in this document is intended to augment or contradict EPA-approved label instructions. Phytosanitary officials and nursery industry members should verify registration/labeling status prior to use of a particular product.
Environmental factors, varietal differences, and stage of growth may have significant effects on phytotoxic expression. When using any pesticide, it is recommended that a small group of plants be treated at the recommended rate under the anticipated growing conditions and observed for phytotoxic symptoms for at least seven days before large numbers of plants are treated.
All treatments will be performed under direct supervision of a phytosanitary official or under compliance agreement.
Treatments and procedures under a compliance agreement will be monitored closely throughout the season. Unless the shipper is operating under a compliance agreement, a state phytosanitary certificate listing and verifying the treatment used must be forwarded to the receiving state via fax or electronic mail, as well as accompanying the shipment. The phytosanitary certificate shall bear the following additional declaration: "The rooted plants were treated to control Popillia japonica according to the criteria for shipment to category 1 states as provided in the U.S. Domestic Japanese Beetle Harmonization Plan." This same wording will be used in the form of a sticker or stamp and will accompany shipments when a shipper is operating under a compliance agreement
On an interim basis, additional treatments may be accepted if the proposed product is appropriately labeled, effectively controls Japanese beetle, and is mutually agreeable to the states involved.
1. Dip Treatment - B&B and Container Plants
Chlorpyrifos (Dursban 4E, Dursban TNP). Apply at a rate of two (2.0) pounds active ingredient (64 ounces) per 100 gallons of water. Only balled and burlapped, potted and containerized nursery stock with rootballs twelve (12) inches in diameter or smaller and consisting of non-clay soil are eligible. The potted or balled and burlapped stock will be dipped so as to submerge the entire root ball and all growing media of the container or the root retaining materials into the solution. The submersion time should be a minimum of two (2.0) minutes and until complete saturation occurs. Upon removal from the solution the plants are drained in an environmentally safe way.
Treatment is to be applied against Japanese beetle larval stages. Treatment must be applied between September 15 and April 15 in southern states and between September 1 and May 1 in the northern states as determined by the appropriate phytosanitary official. Growing media must be at least 50o F at the time of treatment. Medium should be of moderate moisture content (not too wet or not too dry) so that pesticide will adequately penetrate the medium. Plants should not be shipped before they are well drained and can be easily handled. Treated material must be shipped prior to beetle flight, or be protected from re-infestation. During the adult flight period all treated plants must be protected from re-infestation if they are held for more than two weeks before shipment.
2. Drench Treatments - Container Plants Only
Potting media used must be sterile and soilless, containers must be clean. Field potted plants are not eligible for certification using this protocol. This is a prophylactic treatment protocol targeting eggs and early first instar larvae. If the containers are exposed to a second flight season they must be retreated.
Imidacloprid (Marathon 60WP). Apply one-half (0.5) gram of active ingredient per gallon as a prophylactic treatment just prior to Japanese beetle adult flight season (June 1, or as otherwise determined by the phytosanitary official). Apply tank mix as a drench to wet the entire surface of the potting media. A twenty-four (24) gallon tank mix should be enough to treat 120-140 one-gallon containers. Avoid over drenching so as not to waste active ingredient through leaching. During the adult flight season, plants must be retreated after sixteen (16) weeks if not shipped to assure adequate protection.
Bifenthrin (Talstar Nursery Flowable 7.9%). Mix at the rate of twenty (20) ounces per 100 gallons of water. Apply, as a drench, approximately eight (8) ounces of tank mix per six (6) inches of container diameter.
3. Media (Granule) Incorporation - Container Plants Only
All pesticides used for media incorporation must be mixed prior to potting and plants potted a minimum of thirty (30) days prior to shipment. Potting media used must be sterile and soilless, containers must be clean and plants for potting will be free of Japanese beetle. The granules must be incorporated into the media prior to potting. Field potted plants are not eligible for treatment. This treatment protocol targets eggs and early first instar larvae and allows for certification of plants that have been exposed to only one flight season after application. If the containers are to be exposed to a second flight season they must be repotted with a granule incorporated mix or retreated using one of the approved drench treatments. Pesticides approved for media incorporation are:
Imidacloprid (Marathon 1 G). Mix at the rate of five (5) pounds per cubic yard.
Bifenthrin (Talstar Nursery Granular or Talstar T&O Granular (0.2 G)). Mix at the rate of 25 ppm or one-third (0.33) of a pound per cubic yard based on a potting media bulk density of 200. (bulk density = dry weight in pounds of one cubic yard of potting media)).
Tefluthrin (Fireban 1.5 G). Mix at the rate of 25 ppm based on a potting media bulk density of 400. (See above definition of bulk density).
4. Methyl Bromide Fumigation
Nursery stock: methyl bromide fumigation at NAP, chamber or tarpaulin. See the California Commodity Treatment Manual for authorized schedules.
Many plant cultivars may be severely injured by methyl bromide fumigation. To minimize injury, plants should be free of surface moisture. However, pans of water should be placed around the chamber floor to lower the risk of plant damage. The fumigant should be injected into the chamber as a high-temperature (210oF vapor) and not as a liquid. Foliage should not touch the inner sides of the chamber or enclosure, and should be kept out of the direct air blast from the circulating and exhaust fans. For best results, the nursery stock should be at the temperature of the selected schedule prior to treatment. Material treated from October through April must be shipped prior to beetle flight or be protected from re-infestation. During the adult flight period all treated plants must be protected from re-infestation if they are held before shipment.
